Problems solved by technology

Nevertheless, there is no successful research report on carbon nanotube composite electrodeposition process, only W.X.Chen (Carbon, 2003, Vol.41: 215-222) tried to composite electroless Ni-P alloy coating on carbon nanotubes. , which is completely different from the technical approach of directly compounding carbon nanotubes into the metal matrix in this project

Abstract

The invention is a method of preparing nickel-based nano carbon tube composite by compound electric deposition method, using any one of the common plating solution systems able to deposit nickel or nickel alloy as basic plating solutions, adding in nano carbon tube processed by routine purification as additive, thus composing a novel compound plating solution, then according to the general plating/chemical plating operating method, with the help of electrifying or spontaneous chemical reacting course, impelling deposition of nickel or nickel alloy on a certain substrate and making the condeposition of nano carbon tube and metal at the same time, and preparing the finished products. The nano carbon tube can be single-wall nano carbon tube and also multi-wall carbon tube. It has simple technique and prepares high-performance composite with the help of excellent properties of nano carbon tube.

Description

Technical field: [0001] The invention relates to a method for preparing a nickel-based carbon nanotube composite material by composite electrodeposition. Through the electrodeposition method, the carbon nanotube is effectively composited with metal nickel as a structural reinforcement phase to construct a high-performance nanocomposite material, which belongs to composite materials Preparation technology field. Background technique: [0002] Composite electrodeposition is a technique in which insoluble solid particles are uniformly mixed into the metal coating to form a composite material by co-electrodeposition with metal. It includes two types of composite electroplating film and composite electroforming. Among them, composite electroplating can prepare composite thin film materials for surface modification of materials and preparation of thin film composite materials, and composite electroforming is used for thick film composite materials and general composite materials. ...
